⟨E_t⟩ vs. ⟨L_z⟩ (i.e. median total binding energy vs. median angular momentum on the z-axis of the MW, also known as the Lindblad diagram) for the five MMR subgroups (in the same colours as Fig. 2). The Solar group parameters are shown in grey for comparison. All stars seem to be in prograde movement, independently of their group classification, at several levels of binding energy.
